A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. The most common parallel port is a printer port known as the Centronics port.
In the 1980s and 1990s, the parallel port was the standard for connecting printers. With the ascendancy of USB since the late 1990s, though, parallel port technology has faded in popularity. At this point, relatively few computers or other devices even include parallel ports anymore. USB ports, on the other hand, are ubiquitous.
